Answer:
well it won't solve fully I guess 18^2/4^2 x^2 - 50^2/9^2 so we get 324/16x^2- 2500/81y^2
as x and y are different I don't think it'll be solved further

Answer:
Step-by-step explanation:
Given that,
18/4 x power 2 - 50/9 y power 2
= 9/2 x power 2 - 50/9 y power 2 ( ∵ 18/4= 2 × 9 / 2 × 2 = 9/2 )
= (9/2x + 50/9y) ( 9/2x - 50/9y ) ( ∵a square - b square = (a + b ) ( a -b ) )
